=head1 NAME
samba - Plugin to monitor number of files held open by the CIFS clients
=head1 CONFIGURATION
This plugin uses the following configuration variables:
[samba]
user root
env.smbstatus /usr/bin/smbstatus
env.ignoreipcshare 1
Usually "smbstatus" requires to be run as root (see "user root" above).
Environment variables:
* smbstatus: path to "smbstatus" executable
(default: search PATH and fall back to /usr/bin/smbstatus)
* ignoreipcshare: set this variable to any non-empty value to ignore IPC$ when counting shares.
